CAMBRIDGE, Mass., Sept. 15, 2016 /PRNewswire/ -- Trek Therapeutics (TREKtx), a private, clinical stage public benefit corporation developing affordable and accessible treatment regimens for serious infections, today announced the first results from an open-label Phase 2a study of faldaprevir (FDV) plus TD-6450 and ribavirin (RBV). The sustained viral response (SVR) rate four weeks after the completion of treatment (SVR4) was 100 percent (16 of 16) in treatment naïve patients with chronic genotype 4 (GT 4) hepatitis C virus (HCV) who received 120 mg of FDV and RBV in combination with 60 mg or 120 mg of TD-6450 for 12 weeks.
"The results of this study are very encouraging, and consistent with preliminary data from our ongoing Phase 2a study in patients with genotype 1b (GT 1b) HCV," said Robert Hindes, M.D., Chief Medical Officer at Trek Therapeutics. "Our goal is to develop regimens with the potential to play an important role in the treatment of hepatitis C in middle income countries where affordable and accessible treatments for HCV are not readily available."
About the Phase 2a Study
The results announced today are from an open-label Phase 2a study that evaluated two doses of TD-6450, 60 mg or 120 mg QD, in combination with FDV 120 mg QD and RBV for 12 weeks in non-cirrhotic treatment-naïve patients with chronic GT 4 HCV. In this study, there were no serious adverse events or treatment discontinuations, and the majority of adverse events were mild. The most common adverse events observed in greater than 10 percent of patients across the study were fatigue, headache, and nausea. Efficacy results for the two arms of the study were similar, and are combined in the summary below:
One hundred percent (100%, 16/16) of patients had HCV RNA below the lower limit of quantitation (
